This means that the opening of the obturator is offected by a pulling action from the top, but as the reservoir may be located at a certain height to insure the perfect discharge thereof, and therefore the control means cannot be located above the reservoir as it would remain out of reach, the device b constituting the control element is located on the lower portion, so that the box Ill thereof is xed direct to the front wall of the reservoir, as shown in Figures 1 and 2, or to the lower portion of the reservoir, as shown in Figures 3 and 4. However, as with this arrangement it could not operate without sealing means and without the danger of water ltrations, the deriving and transmission means thereof, instead of being directed straight to the liquid mass are directed upwardly enclosed in a protection conduit which renders same entirely independent and isolated from the liquid contained in the reservoir.

For this purpose, the transmission means indicated at c are housed in the conduit d which, due to its application, constitutes the main object of the present invention. Said conduit d is coupled to the box I0 of the control device d so that in the case of Figures 1 and 2, it starts from an opening in the front wall of reservoir a, and in the case of Figures 31 and 4, the conduit d passes through the bottom or wall of the same reservoir. As may be seen in the drawings, the conduit or channel d, after passing through the reservoir is directed vertically upwards towards the upper portion thereof, where said conduit is provided with an opening II located above the upper maximum level of the liquid; thus, the interior of the conduit or channel d is kept perfectly isolated from the liquid, so that the transmission c will operate dry or, if desired, lubricated in the usual manner to render the operation smoother and increase the life of the mechanism. Thus, the independence of the interior of conduit d is insured not only during the normal operation of the apparatus but also in emergency cases, since the mouth II of said conduit is located above the mouth of the overow pipe I2, so that in case the valve 2 should fail, the liquid would flow through said overiiow pipe I2 before reaching the interior of said conduit. y

The device b comprises a button I3 ending in a stem I4 which enters the conduit d and is guided therein on being pressed as shown in Figure 3. Following said stem are a series of segments I5 which may be annular or have the shape of small solid cylinders. The size of the segments I5 will be in accordance with the cross-section of the tubular conduit d, so as to be maintained in correct alignment guided by the walls of the conduit.

'Ihe last segment I5 is connected to the rod I6 guided in the ,upwardly directed portion of the same conduit d and projects through the opening II which, as already stated, is located above the maximum upper water level. Said rod I5 isv turned at an angle of about 189 and extends out of the conduit d in the opposite direction, that is to say, downwardly; by means of a hook I6 said rod is connected to the rod 8, the latter being provided with a head 8' so that on raising the rod I6 the hook I6 will engage said head 8', thereby pulling the rod 8 which brings the obturator 'I upwardly. Said obturator leaves its seat 6 and iioats, causing the discharge of the lwater contained in the reservoir, as shown in Figures 2 and 4.

Therefore, the transmission c is constituted by the segments I5 and rod I6, as through this transmission the action of the button I3 reflects on the obturator 'I to lift same and cause the discharge, and as the rod I6 and segments I5 form a linear column, after pressing the button I3 to open or raise the obturator 'I, the transmission returns to its normal position by its own weight, although this action may be aided with an auxiliary spring I'I so arranged in the controldevice b that it will press the button I3 towards its initial position indicated in Figures 1 and 3. The liquid in rreservoir a passes through the pipe 5 to fthe water closet to which the apparatus has been connected,n and once the water has been entirely eliminated the obturator falls by its own weight on theseat 5 closing the outlet to admit a new charge.y

Instead of segments I5, other elements may constitute the transmission c, provided the latter is housed in the protecting conduit which extends above themaximum liquid level.

It is evident that several modifications in construction and detail may be introduced without departing from the scope of the presentA invenf` tion as clearly set forth in the appended claims. Whatis claimed is:

l. In a valve mechanism for water closets having a reservoir the d ischarge'pipe of which is provided with a float valve dependent upon a transmission responsive to a control button: a transmission formed with a-rod turned at sub'y stantially 180` into an elbow, one arm of said rod acting within a shielding tube serving to avoid the contact thereof with the water, said arm being also coupled to the rest of the transmission responsive to the control button, the other arm of said rod extending downwardly to engage the rod of said float valve.

, 2. In a valve mechanism for water closets having a reservoir the discharge pipe of which is provided with a float valve dependent upon a transmission responsive to a control button: a transmission extending upwardly within a shield' ing tube and turned at substantially 180 into an elbow, directed downwardly and engaging the rod of said oat valve, a po-rtion of said transmission formed by segments housed within the angle or curves of said shielding tub-e, anda control button connected to said transmission segments.

3. In a valve mechanism for water closets having a reservoir the discharge pipe of which is provided with a oat valve dependent upon a transmission responsive to a control button: a rod turned at substantially linto an elbow, forming two arms, one of said arms being housed within a shielding tube and connected to segments dependent upon the control button, andv th-e other of said arms being connected so as to pull and lift the discharge oat valve.
